Alec Baldwin describes kissing actress Jennifer Aniston during her recent guest appearance on his Emmy-winning NBC comedy, 30 Rock, as “painful.”

Baldwin’s character, Jack Donagh, had to smooch the actress’ stalker alter ego Claire Harper, but the 50-year-old actor laments the liplock was not as enjoyable as he had imagined it would be.

“It was painful,” he jokes in this week’s edition of New York Magazine. “I mean, every man who’s had to make out with her in TV and movies – I don’t know how they do it!”
